Filed Aug.- 14, 1962, Ser. No. 216,838 4 Claims. ((31. 101- 36) This invention relates to a method and apparatus for temporarily identifying a line in a printed page of proof which has been changed or corrected subsequent to the printing of a previous proof. More specifically, it relates to a type slug of the same general form as that produced by a conventional typesetting machine, such as a Linotype machine, but which is cast with a readily removable printing projection. Such a type slug is utilized in the method disclosed herein as a substitute fora conventional slug originally incorporated in a page of type. The printing projection provides a temporary identifying symbol for the altered line in the succeeding proof of the printed page, which symbol, in turn, can be readily eliminated prior to the next printing operation by bodily removal of the printing projection from the slug, without otherwise disturbing the set type.

Such an arrangement permits the lines on a printed page, which have been changed from a previous proof, to be readily identified. This, in turn, permits a check of the changes or corrections to be quickly made. When the corrected or changed portions of the type have been approved by examination of such a proof, the printing projections which produce the identifying symbols can be bodily removed from the printing face of the type slugs so that subsequent proofs, or final copy, prepared from the same type will not contain any of the identifying symbols which appeared in the preceding proof.

Such a process of preparing printed material, as described, has been found to be particularly useful in the preparation of legal documents of various kinds, where corrections or changes are often made in the copy subsequent to the preparation of the first printed proof. Comparison of the text of a second printed proof, incorporating such changes or corrections, with the first printed proof, in order to ascertain whether the changes have been properly made, is diificult and tedius since there is ordinarily no indication on the second printed proof of where such changes have been incorporated.

As mentioned, the present method has the distinct advantage of permitting the temporary identification of those lines in which corrections or changes have been made, and the ready removal of the means of printing such identification symbols as soonas the changes so incorporated have been approved. This permits the type which has been used to print the corrected proof to be quickly readied for use in printing the final copy, which is a significant advantage when documents are involved that have filing deadlines, as is often the case in the legal and financial fields.

Further objects and advantages of this invention will become evident as the description proceeds and from an examination of the accompanying drawing which illustrates one embodiment of the invention and in which similar numerals refer to similar parts throughout the 3,136,248 Patented June 9, 1964 printed material from the same assembly of type slugs from which the sheet shown in FIGURE 3 was prepared except that the printing projections associated with a portion of the slugs have been removed.

Referring now to FIGURE 1, a type slug identified generally by the numeral 10 is shown therein of the same general form as that normally obtained from a Linotype machine or similar typesetting apparatus adapted to cast lines of type in the form of a slug. The slug has the form of an elongated rectangle, in general configuration, and relatively thin. It is provided on one of its narrow faces 12 with a plurality of integrally cast type characters, indicated generally by the numeral 14. These type characters normally will produce one line of print in whatever printed characters 14. This projection 16 preferably is in the form of very narrow, upstanding bar of type metal formed integrally with the slug 10, so that in the printing operation it forms a symbol in the form of a short vertical line disposed in spaced relation to the main body of the line of print produced by the type 14 on the slug. Obviously the projection 16 could take any other suitable form, insofar as the nature of the printed symbol produced thereby is concerned. However, it should have a configuration such that itis readily removable from the face of the slug by the use of a simple tool having an edge capable of cutting off the metal forming the projection 16 from the body of the slug when manually applied thereto.

As shown in FIGURE 2, the type 14 is normally cast with a base portion 18 forming what might be termed a pedestal for the type characters. This base or pedestal is formed integrally with each type character, and contiguous characters preferably have their bases unitedto form a common base portion. The printing projection 16, on the other hand, is not privided with any such base or pedestal portion. The absence of such a base portion in the printing projection 16 makes it more readily removable from the face of the slug 12. Fortunately, it has been found to be unnecessary to have such a base portion in the printing projection, since a relatively small number of printed copies are normally made while the projection is still in place. On the other hand, the type characters must have a construction firm enough to insure repeated use in the process of printing.

As previously mentioned, a portion of a printed proof, indicated generally by the numeral 20, made from a page of type in which some of the lines have been corrected is illustrated in FIGURE 3. As shown therein, the printed copy is made up of a plurality of lines of print 22 and in the left hand margin of the page there appears a vertical line symbol 24 in association with lines which thus are indicated as having been corrected or changed. As can be seen from that representation, it is readily apparent to an observer which lines of the copy have bene changed. These lines can, therefore, be quickly compared with the previous page proof to confirm the fact that the corrections have been made properly.

The portion of the printed page proof shown in FIG- URE 4, indicated generally by the numeral 26, is a page corresponding to the page shown in FIGURE 3 except that it is a proof which has been run subsequent to the removal of the printing projections 16 which produced the symbols 24 on the page 20 shown in FIGURE 3. It

should be noted that the printed lines 22 in both page proofs shown in FIGURES 3 and 4 are identical, except that the identification symbols are absent in proof 26,

shown in FIGURE 4. The page proof shown in FIGURE 9 4 could therefore be the final copy, if no more corrections needed to be made. This means, of course, that the same type could be used to print the final copy aswas used to print the corrected page proof 20 shown in FIGURE 3, after the removal of the printing projection 16. .The identification of changed lines can, therefore, be accomplished temporarily, but the same type can be'used for subsequent copy without such identification.

In the drawing and specification, there has been set 'forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic'and descriptive sense only and not for purposes of limitation. Changes in form and in the proportion of parts, as well as the substitution of equivalents are contemplated, as circumstances may suggest or render expedient, without departing from the spirit or scope of this invention as further defined in the following claims.

I claim: 1. The method of temporarily identifying a corrected line of print in a. succeeding proof sheet of material previously printed comprising: casting a corrected type slug having the printed matter for said line with a readily removable printing projecion formed integrally therewith said substituted slug being provided With a readily remov-.

able printing projection adapted to print a temporary identifying symbol in association with the line of print printed from said substituted slug and printing a new sheet of printed matter from said plurality of type slugs.

- 3. The method of preparing multiple proofs of a sheet of printed matter which comprises the steps of casting a plurality of slugs each incorporating a line of type, assembling said slugs to form a page of type, preparing a printed proof of said page from said type, removing at least one of the original type slugs, recasting and substituting a replacement type slug for each said original type slug removed, each said replacement type slug being provided with a readily removable printing projection adapted to print an identifying symbol in association with the line of type printed by said replacement type slug, preparing a second proof of said page from said type including said substituted type slug and subsequently removing said printing projection from said substituted type slug prior to additional printing.

4. A type slug which comprises an elongated main body portion, a line of cast type formed integrally on one of the faces of said body portion, and a printing projection secured to said face and adapted to print a temporary identifying symbol in association with a line printed from said cast type, said printing projection having a relatively narrow base portion so as to readily permit the removal thereof from said face.
